Perhaps you should try some spelling variations:
wei reformen » der reformen, den reformen, iii reformen
nach david » saah david, macher david
you xiang » you liang, you xian
xiang wei » liang wei, zhang wei, wang wei
hong ng » hong jong, hong hong
kong » long, pong, ong
hai » hadi, haji, hari

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: can you xiang wei reformen nach david ((((hong ng) OR (hong kong))) OR (dang hai)) ;~.
• Adding a wildcard symbol may retrieve word variants: can you xiang wei reformen nach david ((((hong ng) or (hong kong))) or (dang hai)) ;*.
